在278-313 K、5-80 Torr的压力范围内，用光腔衰荡法测定了碘甲烷与氧气反应生成IO自由基的速率常数。在30 Torr总压下，室温速率常数为（4.0 ′ 0.4）× 10 - 13 cm 3 molecule - 1 s - 1.没有观察到显着的温度和总压的依赖性。在100 Torr的N2稀释剂总压下，由CH 2 I + O2合成IO的产率估计为1.
The rate constants of IO radical formation from the reaction of CH 2 I with O 2 were determined in the pressure range of 5-80 Torr with N 2 diluent at 278-313 K, using cavity ring-down spectroscopy. The room temperature rate constant is (4.0 ′ 0.4) x 10 - 1 3 cm 3 molecule - 1 s - 1 at 30 Torr total pressure. No significant dependences on temperature and total pressure were observed. The yield of IO from CH 2 I + O 2 was estimated to be unity in 100 Torr total pressure of N 2 diluent.
